Description

Technical Field

[0001] The present invention belongs to the technical field of electric power marketing, and in particular, relates to a method and system for linking market-oriented attribute changes of industrial and commercial users with electricity fee settlement. Background Art

[0002] As relevant documents on further deepening the market-oriented reform of coal-fired power generation on-grid electricity prices are issued, industrial and commercial users are encouraged to enter the electricity market on a quarterly basis. For industrial and commercial users who have not yet entered the market, power grid companies will act as agents to purchase electricity. For the three types of power purchasing agents who are high energy consumers, have coal-fired self-contained power plants, or have entered the market but have no legitimate reason to withdraw, the power purchasing agent price of ordinary power purchasing users will be 1.5 times.

[0003] After this reform, the dimensions of the market attributes of power users have increased, and at the same time, information of some dimensions needs to be identified and provided by the power trading center. In the prior art, data interaction is mainly carried out through offline lists and several verifications. Faced with tens of millions of power users, the efficiency of power grid companies in maintaining the market attributes of power users has been greatly reduced. The application method of electricity fee risk prevention and control based on power customer tags (CN106845747B) establishes basic tags for each user, and then determines the corresponding electricity fee risk prevention and control process for the customer by identifying the basic tags.

[0004] On the other hand, the purpose of the market-oriented attribute change of power users is to provide a basis for executing electricity prices for electricity bill settlement. In the electricity bill risk prevention and control application method based on power customer tags (CN106845747B), in order to realize the association between the customer's corresponding electricity bill risk prevention and control process and basic tags, it is also necessary to generate complex tags, and then identify the complex tags to update the electricity bill risk prevention and control process. That is, the current market-oriented attribute change of power users and electricity bill settlement cannot be carried out at the same time, otherwise the change of market-oriented attributes of power users will cause power users to execute the wrong electricity price when settling electricity bills. In short, there is a lack of a smooth connection method between the market-oriented attribute change of power users and electricity bill settlement. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a method and system for connecting the market-oriented attribute changes of industrial and commercial users with electricity fee settlement, creating a market-oriented status representation that uniquely corresponds to the electricity consumption information of industrial and commercial users within a certain period of time, and there is a time synchronization relationship between the market-oriented status representation and the electricity fee.

[0006] The present invention adopts the following technical solution.

[0007] On the one hand, the present invention proposes a method for linking the market-oriented attribute change of industrial and commercial users with electricity fee settlement, including:

[0008] Step 1: Generate a unique marketization status representation for industrial and commercial users based on an interaction mechanism; the determining factors of the marketization status representation include: one marketization attribute label and three marketization attribute discrimination fields; among them, the marketization attribute label includes: label effective timestamp and label expiration timestamp; the marketization attribute discrimination fields include: field effective timestamp and field expiration timestamp;

[0009] Step 2: When settling the electricity charges generated by industrial and commercial users during the historical time period [t m ,t n at time point T, use a sliding time window to monitor one by one the moments t i when the marketization status representation of industrial and commercial users changes, where i = 1, 2... N; among them, t m <t i <t n <T, and N is the total number of moments;

[0010] Use the moment t i to divide the historical time period [t m ,t n into multiple sub-time periods, and within each sub-time period, use the effective marketization attribute label and the effective marketization attribute discrimination fields to determine the marketization status representation of industrial and commercial users in the corresponding sub-time period;

[0011] Step 3: Within each sub-time period, determine the user electricity price according to the marketization status representation of industrial and commercial users;

[0012] Step 4: Use the user electricity prices of each sub-time period to settle the electricity charges of industrial and commercial users during the historical time period [t m ,t n .

[0013] The marketization attribute label also includes: registered but untraded users, direct market purchase users, market retail users, and agency power purchase users;

[0014] The marketization attribute discrimination fields also include: whether delisted without justifiable reasons, whether a high-energy-consuming enterprise, and whether having a coal-fired self-provided power plant.

[0015] Within different time periods, the marketization status representation of each industrial and commercial user consists of one effective marketization attribute label and three effective marketization attribute discrimination fields, and at the same time, the marketization attribute label and the marketization attribute discrimination fields are independent of each other.

[0016] Step 1 includes:

[0017] Step 1.1: When industrial and commercial users register, the power trading center pushes the user registration information to the power grid company. The moment when the power trading center pushes the user registration information to the power grid company is the first time when the label takes effect. The first time when the label takes effect corresponds to the moment when the market attribute label of the industrial and commercial user is changed from "agent power purchase user" to "registered non-trading user";

[0018] Step 1.2: When an industrial or commercial user applies for market entry, the power trading center pushes the user's market entry application request to the power grid company through the verification interface, and the power grid company returns to the power trading center whether the user meets the market entry conditions;

[0019] If yes, the power trading center will push the user's market entry information to the power grid company. The moment when the power trading center pushes the user's market entry information to the power grid company is the second time when the label takes effect. The second time when the label takes effect corresponds to the moment when the market attribute label of the industrial and commercial user is changed from "registered non-trading user" to "market direct purchase user" or "market retail user", which is also the first time when the label is invalid.

[0020] If not, the power trading center will not push the user entry information to the power grid company, the market attribute label of the industrial and commercial user will remain unchanged, and the label will remain unchanged when it takes effect;

[0021] Step 1.3, after the market-based attribute label takes effect, the weight of the market-based attribute discrimination field is divided using the weight classification method based on the TF-IDF algorithm; the weight obtained by the division and the weighted sum of the market-based attribute discrimination field are used as the electricity consumption information of the "market direct purchase user" or "market retail user"; wherein, when the weight classification is performed based on the TF-IDF algorithm, the moment when the corresponding weight of any market-based attribute discrimination field is not 0 is used as the field effective time stamp of the market-based attribute discrimination field, and the moment when the corresponding weights of all market-based attribute discrimination fields are 0 is used as the field invalidation time stamp of the market-based attribute discrimination field;

[0022] Step 1.4: When a "market direct purchase user" or "market retail user" changes its electricity consumption information, the power grid enterprise submits a request for electricity consumption information change to the power trading center, repeats step 1.3 to update the weights, and obtains the updated electricity consumption information of the "market direct purchase user" or "market retail user". The power trading center feeds back the market-based attribute discrimination field to the power grid enterprise based on the updated electricity consumption information;

[0023] Step 1.5, when a "market direct purchase user" or "market retail user" applies for delisting, the power trading center pushes the user delisting request to the power grid enterprise, the "whether delisting is without a legitimate reason" in the market-based attribute judgment field is "No", and the field effectiveness time stamp of "whether delisting is without a legitimate reason" is "No"; the moment when the power grid enterprise pushes the market-based attribute label of the industrial and commercial user to the power trading center from "market-based direct purchase user" or "market-based retail user" to "agent power purchase user" is the third effective time of the label, and at the same time, the "whether delisting is without a legitimate reason" in the market-based attribute judgment field is changed from "No" to "Yes", and the field effectiveness time stamp is updated with the third effective time of the label.

[0024] In step 1.3, using the weighted classification method based on the TF-IDF algorithm, M(P, W) is used to represent the number of times a market-based attribute discrimination field W is used to mark user P, TF(P, W) is used to represent the proportion of the number of times a market-based attribute discrimination field W is used in all market-based attribute discrimination fields of user P, and IDF(P, T) is used to represent the scarcity of any market-based attribute discrimination field W in all market-based attribute discrimination fields, that is, the probability of occurrence of the market-based attribute discrimination field W; the weight value of any market-based attribute discrimination field W of the user is obtained according to TF(P, W)×IDF(P, T).

[0025] Specifically, step 2 includes:

[0026] Step 2.1: For the historical time period of industrial and commercial users [t m ,t n ], using the sliding time window to monitor the time t when the marketization status representation of industrial and commercial users changes one by one i , i=1,2…N;

[0027] Step 2.2, using time t i The historical time period [t m ,t n ] is divided into multiple sub-time periods [t m ,t 1 ]、[t 1 ,t 2 ], ..., [t i ,t i+1 ], ..., [t N ,t n ];

[0028] Step 2.3, in each sub-time period, using an effective market attribute label and three effective market attribute discrimination fields, determine the market status representation of the industrial and commercial users in the corresponding sub-time period; wherein the market status representation of the industrial and commercial users in each sub-time period is unique.

[0029] In step 2.1,

[0030] In any sliding time window, if the marketization attribute label or any marketization attribute discriminant field changes, it is determined that the marketization state representation of the commercial user in the sliding time window has changed;

[0031] In any sliding time window, although the marketization attribute label and any marketization attribute discrimination field have changed, if the marketization attribute label fails or any marketization attribute discrimination field fails, it is determined that the marketization status representation of the commercial user in the sliding time window has changed;

[0032] Among them, the label effective time stamp and label invalid time stamp of the market-oriented attribute label are compared with the sliding time window to determine whether the market-oriented attribute label is invalid within the sliding time window, and the field effective time stamp and field invalid time stamp of any market-oriented attribute discrimination field are compared with the sliding time window to determine whether any market-oriented attribute discrimination field is invalid within the sliding time window.

[0033] In step 3, in any sub-time period, when the market-oriented attribute label of the industrial and commercial user is effective and is an "agent electricity purchasing user" or a "registered non-trading user", the corresponding value of the market-oriented attribute label is 10; when the market-oriented attribute label of the industrial and commercial user is effective and is a "market-oriented direct purchasing user" or a "market-oriented retail user", the corresponding value of the market-oriented attribute label is 00; when the market-oriented attribute label of the industrial and commercial user is invalid, the corresponding value of the market-oriented attribute label is 00.

[0034] In step 3, in any sub-time period, when the three market-based attribute discrimination fields of the industrial and commercial user are all effective and at least one market-based attribute discrimination field is "yes", the corresponding value of the market-based attribute discrimination field is 01; when the three market-based attribute discrimination fields of the industrial and commercial user are all effective but at least one market-based attribute discrimination field is "no", the corresponding value of the market-based attribute discrimination field is 00; when any market-based attribute discrimination field of the industrial and commercial user is invalid, the corresponding value of the market-based attribute discrimination field is 00.

[0035] The corresponding value of the marketization status representation of the industrial and commercial user is the sum of the corresponding value of the effective marketization attribute label and the corresponding value of the effective marketization attribute discrimination field.

[0036] When the corresponding value of the market status representation of industrial and commercial users is 11, the user's electricity price is 1.5 times the proxy electricity purchase price; when the corresponding value of the market status representation of industrial and commercial users is 10, the user's electricity price is the proxy electricity purchase price; when the corresponding value of the market status representation of industrial and commercial users is 01 or 00, the user's electricity price is the user's contract price.

[0037] Historical time period of industrial and commercial users [tm , t n the electricity charge F within [tm,tn] satisfies the following relational expression:

[0038]

[0039] wherein, respectively represent the electricity price of the user in the sub - time period [t m , t 1 , the electricity price of the user in the sub - time period [t 1 , t 2 , the electricity price of the user in the sub - time period [t i , t i+1 , the electricity price of the user in the sub - time period [t N , t n , and the electricity price of the user in the sub - time period [t

[0040] On the other hand, the present invention also proposes a connection system for the market - oriented attribute change and electricity charge settlement of industrial and commercial users, including: a market - oriented state characterization module, a user electricity price module, and an electricity charge settlement module;

[0041] The market - oriented state characterization module is used to generate a unique market - oriented state characterization for industrial and commercial users; the determining factors of the market - oriented state characterization include: a market - oriented attribute label and three market - oriented attribute discriminant fields; when settling the electricity charge generated by industrial and commercial users in the historical time period [t m , t n at the time point T, use a sliding time window to monitor the moment t when the market - oriented state characterization of industrial and commercial users changes one by one i , i = 1, 2... N; wherein, t m < t i < t n < T, and N is the total number of moments; use the moment t i to divide the historical time period [t m , t n into multiple sub - time periods, and use the effective market - oriented attribute label and effective market - oriented attribute discriminant fields within each sub - time period to determine the market - oriented state characterization of industrial and commercial users in the corresponding sub - time period;

[0042] The user electricity price module is used to determine the user electricity price according to the market - oriented state characterization of industrial and commercial users within each sub - time period;

[0043] The electricity charge settlement module is used to settle the electricity charge of industrial and commercial users in the historical time period [t m , t n by using the user electricity price of each sub - time period.

[0044] The beneficial effect of the present invention is that, compared with the existing technology, it can support power grid enterprises to accurately and clearly store the market attributes of electricity users, efficiently and smoothly exchange information data on changes in the market attributes of electricity users with power trading centers, and effectively connect the changes in the market attributes of electricity users with electricity fee settlement work.

[0045] The present invention constructs a time-stamped market status representation for industrial and commercial users through an online data interaction mechanism between power grid enterprises and trading centers. Within a certain period of time, the market status representation uniquely corresponds to the power consumption information of industrial and commercial users, so that the market status representation can be fully utilized to identify user information and handle related businesses. In the face of tens of millions of power users, the efficiency of power grid enterprises in maintaining the market attributes of power users is improved.

[0046] The market-oriented state representation is a continuous state quantity of the user's electricity consumption state based on the time axis, and is closely connected with the electricity bill settlement, realizing the synchronization of the market-oriented attribute changes of the power user and the electricity bill settlement in time, which is conducive to the real-time promotion of the electricity bill settlement work, reducing the electricity bill prevention and control risks of the power grid enterprises, reducing the error rate in the user's electricity bill settlement, and supporting the efficient operation of the power grid enterprises and trading centers.

[0047] Figure 1 It is a flow chart of the method for linking the market-oriented attribute change and electricity fee settlement of industrial and commercial users proposed by the present invention;

[0048] Figure 2 This is a flow chart of generating a unique market status representation for industrial and commercial users based on an interactive mechanism in an embodiment of the present invention. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only embodiments of a part of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0050] On the one hand, the present invention proposes a method for linking the market-oriented attribute change of industrial and commercial users with electricity fee settlement, such as Figure 1 As shown, including:

[0051] Step 1: Generate a unique market status representation for industrial and commercial users based on the interactive mechanism; the determining factors of the market status representation include: a market attribute label and three market attribute discrimination fields;

[0052] Among them, market-based attribute labels include: registered non-trading users, market-based direct purchase users, market-based retail users, agent power purchase users, label effective time stamp, label expiration time stamp;

[0053] The market-based attribute identification fields include: whether the company is delisted without a legitimate reason, whether it is a high-energy-consuming enterprise, whether it has a coal-fired self-contained power plant, the time stamp of the field taking effect, and the time stamp of the field becoming invalid;

[0054] In different time periods, the marketization status representation of each industrial and commercial user consists of an effective marketization attribute label and three effective marketization attribute discrimination fields. At the same time, the marketization attribute label and the marketization attribute discrimination fields are independent of each other.

[0055] The present invention generates a unique market status representation for industrial and commercial users based on an interactive mechanism.

[0056] Step 1, such as Figure 2 ,include:

[0057] Step 1.1: When industrial and commercial users register, the power trading center pushes the user registration information to the power grid company. The moment when the power trading center pushes the user registration information to the power grid company is the first time when the label takes effect. The first time when the label takes effect corresponds to the moment when the market attribute label of the industrial and commercial user is changed from "agent power purchase user" to "registered non-trading user";

[0058] Step 1.2: When an industrial or commercial user applies for market entry, the power trading center pushes the user's market entry application request to the power grid company through the verification interface, and the power grid company returns to the power trading center whether the user meets the market entry conditions;

[0059] If yes, the power trading center will push the user's market entry information to the power grid company. The moment when the power trading center pushes the user's market entry information to the power grid company is the second time when the label takes effect. The second time when the label takes effect corresponds to the moment when the market attribute label of the industrial and commercial user is changed from "registered non-trading user" to "market direct purchase user" or "market retail user", which is also the first time when the label is invalid.

[0060] If not, the power trading center will not push the user entry information to the power grid company, the market attribute label of the industrial and commercial user will remain unchanged, and the label will remain unchanged when it takes effect;

[0061] Step 1.3, after the market-based attribute label takes effect, the weight of the market-based attribute discrimination field is divided using the weight classification method based on the TF-IDF algorithm; the weight obtained by the division and the weighted sum of the market-based attribute discrimination field are used as the electricity consumption information of the "market direct purchase user" or "market retail user"; wherein, when the weight classification is performed based on the TF-IDF (Term Frequency–Inverse Document Frequency) algorithm, the moment when the corresponding weight of any market-based attribute discrimination field is not 0 is used as the field effective time stamp of the market-based attribute discrimination field, and the moment when the corresponding weights of all market-based attribute discrimination fields are 0 is used as the field invalidation time stamp of the market-based attribute discrimination field;

[0062] In the weighted classification method based on the TF-IDF algorithm, M(P, W) is used to represent the number of times a market-based attribute discriminant field W is used to mark user P, TF(P, W) is used to represent the proportion of the number of times a market-based attribute discriminant field W is used in all market-based attribute discriminant fields of user P, and IDF(P, T) is used to represent the scarcity of any market-based attribute discriminant field W in all market-based attribute discriminant fields, that is, the probability of occurrence of market-based attribute discriminant field W. If the probability of occurrence of market-based attribute discriminant field W is very small and it is used to mark a certain user at the same time, this makes the relationship between the user and the market-based attribute discriminant field W closer. The weight value of any market-based attribute discriminant field W of the user is obtained according to TF(P, W)×IDF(P, T).

[0063] Step 1.4: When a "market direct purchase user" or "market retail user" changes its electricity consumption information, the power grid enterprise submits a request for electricity consumption information change to the power trading center, repeats step 1.3 to update the weights, and obtains the updated electricity consumption information of the "market direct purchase user" or "market retail user". The power trading center feeds back the market-based attribute discrimination field to the power grid enterprise based on the updated electricity consumption information;

[0064] Step 1.5, when a "market direct purchase user" or "market retail user" applies for delisting, the power trading center pushes the user delisting request to the power grid enterprise, the "whether delisting is without a legitimate reason" in the market-based attribute judgment field is "No", and the field effectiveness time stamp of "whether delisting is without a legitimate reason" is "No"; the moment when the power grid enterprise pushes the market-based attribute label of the industrial and commercial user to the power trading center from "market-based direct purchase user" or "market-based retail user" to "agent power purchase user" is the third effective time of the label, and at the same time, the "whether delisting is without a legitimate reason" in the market-based attribute judgment field is changed from "No" to "Yes", and the field effectiveness time stamp is updated with the third effective time of the label.

[0065] Through the online data interaction mechanism between power grid enterprises and trading centers, the present invention constructs a time-stamped market-oriented status representation for industrial and commercial users. Within a certain time period, the market-oriented status representation uniquely corresponds to the electricity consumption information of industrial and commercial users, so that the user information can be fully utilized to identify the user information and handle relevant services. Facing tens of millions of power users, the efficiency of power grid enterprises in maintaining the market-oriented attributes of power users is improved.

[0066] Step 2, when settling the electricity charges generated by industrial and commercial users in the historical time period [t m ,t n at time point T, use a sliding time window to monitor one by one the moment t when the market-oriented status representation of industrial and commercial users changes i , i = 1, 2... N; where t m <t i <t n <T, and N is the total number of moments.

[0067] Use the moment t i to divide the historical time period [t m ,t n into multiple sub-time periods, and use the effective market-oriented attribute labels and effective market-oriented attribute discrimination fields within each sub-time period to determine the market-oriented status representation of industrial and commercial users in the corresponding sub-time period.

[0068] Specifically, step 2 includes:

[0069] Step 2.1, for the historical time period [t m ,t n of industrial and commercial users, use a sliding time window to monitor one by one the moment t when the market-oriented status representation of industrial and commercial users changes i , i = 1, 2... N;

[0070] Within any sliding time window, if the market-oriented attribute label or any market-oriented attribute discrimination field changes, it is determined that the market-oriented status representation of commercial users within the sliding time window changes;

[0071] Within any sliding time window, although both the market-oriented attribute label and any market-oriented attribute discrimination field change, but the market-oriented attribute label fails or any market-oriented attribute discrimination field fails, it is determined that the market-oriented status representation of commercial users within the sliding time window changes;

[0072] Among them, the label effective time stamp and label invalid time stamp of the market-oriented attribute label are compared with the sliding time window to determine whether the market-oriented attribute label is invalid within the sliding time window, and the field effective time stamp and field invalid time stamp of any market-oriented attribute discrimination field are compared with the sliding time window to determine whether any market-oriented attribute discrimination field is invalid within the sliding time window.

[0073] Step 2.2, using time t i The historical time period [t m ,t n ] is divided into multiple sub-time periods [t m ,t 1 ]、[t 1 ,t 2 ], ..., [t i ,t i+1 ], ..., [t N ,t n ];

[0074] Step 2.3, in each sub-time period, using an effective marketization attribute label and three effective marketization attribute discrimination fields, determine the marketization status representation of the industrial and commercial users in the corresponding sub-time period.

[0075] The marketization status of industrial and commercial users in each sub-time period is uniquely represented.

[0076] The market-oriented state representation proposed in the present invention is a continuous state quantity of the user's electricity consumption state based on the time axis, and is closely connected with the electricity fee settlement, thereby realizing the synchronization of the market-oriented attribute changes of the power user and the electricity fee settlement in time, which is conducive to the real-time promotion of the electricity fee settlement work, reduces the electricity fee prevention and control risks of the power grid enterprises, reduces the error rate in the user's electricity fee settlement, and supports the efficient operation of the power grid enterprises and the trading center.

[0077] Step 3: In each sub-time period, the user electricity price is determined according to the market status representation of the industrial and commercial users.

[0078] Specifically, in any sub-time period, when the market-oriented attribute label of the industrial and commercial user is effective and is an "agent electricity purchasing user" or a "registered non-trading user", the corresponding value of the market-oriented attribute label is 10; when the market-oriented attribute label of the industrial and commercial user is effective and is a "market-oriented direct purchasing user" or a "market-oriented retail user", the corresponding value of the market-oriented attribute label is 00; when the market-oriented attribute label of the industrial and commercial user is invalid, the corresponding value of the market-oriented attribute label is 00.

[0079] In any sub-time period, when the three market-based attribute discrimination fields of industrial and commercial users are all effective and at least one market-based attribute discrimination field is "yes", the corresponding value of the market-based attribute discrimination field is 01; when the three market-based attribute discrimination fields of industrial and commercial users are all effective but at least one market-based attribute discrimination field is "no", the corresponding value of the market-based attribute discrimination field is 00; when any market-based attribute discrimination field of an industrial and commercial user is invalid, the corresponding value of the market-based attribute discrimination field is 00.

[0080] The corresponding value of the marketization status representation of the industrial and commercial user is the sum of the corresponding value of the effective marketization attribute label and the corresponding value of the effective marketization attribute discrimination field.

[0081] When the corresponding value of the market status representation of industrial and commercial users is 11, the user's electricity price is 1.5 times the proxy electricity purchase price; when the corresponding value of the market status representation of industrial and commercial users is 10, the user's electricity price is the proxy electricity purchase price; when the corresponding value of the market status representation of industrial and commercial users is 01 or 00, the user's electricity price is the user's contract price.

[0082] Step 4: Using the electricity prices of users in each sub-time period, the historical time period [t m ,t n ] within the electricity bill will be settled.

[0083]

[0084] In the formula, Respectively represent the sub-time period [t m ,t 1 ], the user electricity price, sub-time period [t 1 ,t 2 ], the user electricity price, sub-time period [t i ,t it1 ], the user electricity price, sub-time period [t N ,t n ]’s electricity price for users.

[0085] On the other hand, the present invention also proposes a system for linking the market-oriented attribute change and electricity fee settlement of industrial and commercial users, including: a market-oriented state representation module, a user electricity price module, and an electricity fee settlement module;

[0086] The marketization status representation module is used to generate a unique marketization status representation for industrial and commercial users; the determining factors of the marketization status representation include: a marketization attribute label, three marketization attribute discrimination fields; the historical time period [t m ,t nWhen settling the electricity charges generated, use a sliding time window to monitor the moment t when the marketization status representation of industrial and commercial users changes one by one i , i = 1, 2…N; where t n <t i <t n <T, and N is the total number of moments; use the moment t i to divide the historical time period [t m , t n into multiple sub - time periods, and use the effective marketization attribute tags and effective marketization attribute discriminant fields within each sub - time period to determine the marketization status representation of industrial and commercial users in the corresponding sub - time period;

[0087] A user electricity price module, used to determine the user electricity price according to the marketization status representation of industrial and commercial users within each sub - time period;

[0088] An electricity charge settlement module, used to settle the electricity charges of industrial and commercial users within the historical time period [t m , t n by using the user electricity prices of each sub - time period.

[0089] The beneficial effect of the present invention is that, compared with the prior art, it can support power grid enterprises to accurately and clearly store the marketization attributes of power users, efficiently and smoothly carry out data interaction of marketization attribute change information of power users with the power trading center, and effectively connect the marketization attribute change of power users with the electricity charge settlement work.
